Balluay is one of the six requisite barangays established for the founding of the municipality of Sablan, Benguet Province on the 23rd day of November, 1900.
In May 1971, Barangay Balluay was divided into two barangays: Balluay as the mother barangay and Bagong as the new created Barangay, through Republic Act 5676.
In the early days, food would be produced through kaingin or “uma”, such as upland rice, ube, togue, banana, gabi, and camote. A man by the name Mr. Etas from Salat, Kapangan married the daughter of Mr. Pantal and introduced how to improve rice fields. Because of this, the production of rice improved.
The Pantal families were the first settlers in Balluay, followed by Bitalion Kibot from Buguias, Omas Ampaguey from Bineng, La Trinidad and Canuto family from Tuel, Tublay and the Caluagen and Punok families.
